Part IXVisualization with Nam - The NetworkAnimator389
Chapter 45Nam45.1 IntroductionNam is a Tcl/TK based animation tool for viewing network simulation traces and real world packet tracedata. The designtheory behind nam was to create an animator that is able to read large animation data sets and be extensible enough so that itcould be used indifferent network visualization situations. Under this constraint nam was designed to read simple animationevent commands from a large trace file. In order to handle large animtion data sets a minimum amount of information is keptin memory. Event commands are kept in the file and reread from the file whenever necessary.The first step to use nam is to produce the trace file. The trace file contains topology information, e.g., nodes, links, as wellas packet traces. The detailed format is described in the section 46.1. Usually, the trace file is generated by ns. During anns simulation, user can produce topology configurations, layout information, and packet traces using tracing events in ns.However any application can generate a nam trace file.When the trace file is generated, it is ready to be animated by nam. Upon startup, nam will read the tracefile, create topology,pop up a window, do layout if necessary, and then pause at time 0. Through its user interface, nam provides control over manyaspects of animation. These functionalities will be described in detail in the USER INTERFACE section.There are bugs in nam however each successive has become much more stable than the previous one. Please mail nsusers@isi.eduif you encounter any bugs, or have suggestions for addiotional desired functionality.45.2 Nam Command Line Optionsnam [ -g ] [ -t ] [ -i ] [ -j ][ -k ] [ -N ] [ -c ][ -f ] [ -r initial animation rate ][ -a ] [ -p ] [ -S ][ ]Command Line Options390
